Abstract

Technologia produkcji prefabrykatów betonowych za pomocą mieszanki betonu, charakteryzuje się tym, że mieszankę o zawartości 11,52% cementu, 2,65% zeolithu, 36,76% kruszywa drobnego o frakcji 0-2, 44,43% kruszywa grubego o frakcji 2-8, 4,56%, wody zarobowej, 0,04% domieszki chemicznej HC 2 (SIKA), 0,03%, domieszki chemicznej HC 200 (SIKA), dozuje się do mieszalnika w kolejności kruszywo i wodę z dodatkiem zeolitu, następnie domieszkę chemiczną oraz cement, następnie składniki miesza się przez 45 sekund, w temperaturze 5-25°C, po czym zawibrowuje się w wibroprasie przez okres 10-15 sekund i umieszcza się w formie a następnie w komorze klimatycznej gdzie masę poddaje hydratacji przez 12 h w temperaturze 30°C i wilgotności powietrza 70-90%, a następnie suszy się.The technology of producing precast concrete with a concrete mix is characterized by the fact that the mix contains 11.52% cement, 2.65% zeolith, 36.76% fine aggregate with fraction 0-2, 44.43% coarse aggregate with fraction 2 -8, 4.56%, mixing water, 0.04% chemical admixture HC 2 (SIKA), 0.03%, chemical admixture HC 200 (SIKA), dosed to the mixer in the order aggregate and water with the addition of zeolite, then chemical admixture and cement, then the ingredients are mixed for 45 seconds at a temperature of 5-25 ° C, then vibrated in a vibropress machine for a period of 10-15 seconds and placed in a mold and then in a climate chamber where the mass is hydrated for 12 hours temperature 30 ° C and air humidity 70-90%, and then dried.
